• How to avoid using the library native ttJdbcCS when connecting to remote host?

  I'm testing the Java program with the product that limits the use of native libraries.
  I use the 'client' mode to connect to TimesTen DB (which is done by using the plug, not the shared memory).
  
  It seems that even in client mode TimesTen JDBC driver calls the library native ttJdbcCS when doing remote queries.
  Why it does not use Java sockets? What is necessary for the native library?
  Is it possible to eliminate the use of native libraries in client mode of the JDBC TimesTen driver somehow?

  I fear that it is not possible to eliminate the use of native code for TimesTen libraries. Both direct drivers and customer are drivers of type 1 (JDBC/ODBC bridge). In both cases the JDBC driver Java code called NYI optimization library ttJdbc/ttJdbcCS and that the library in the direct or client ODBC driver (also called native code).

  If you want to use TimesTen then you must be able to allow the use of these native code libraries. The only other alternative is to implement your own client/server mehcanism such that you can put your own component 'server' on the machine running TimesTen and then use pure Java to communicate with this component of the 'customer '. Generally, it is however a lot of work.

• How to disable Edit/Clone/case when transaction obtained ceratin in apex 4.2

  Hi all

  In our application, we have designed a screen using interactive report as shown below, in this report when they click on the checkbox and click the middle button we are what makes this transaction as being inactive and red color display. Requirement is now this line had to be disabled once the record was ceratin.

  1. below is screenshot of reference

  

  2 when they select the checkbox and click the ceratin that she will change in different as on the first row, now that the rank we now need to disable this, since this product has been produced de-activated.

  3 below used concept to achieve color, using dynamic action, we put in place this

  $('td[headers="Active_Flag"]').each(function() {  
    if ( $(this).text() === 'N' ) {  
      $(this).closest('tr').find('td').css({"background-color":"#EEA196"});
    } 
  });
  

  4. the logic of inactive code

  update t_test
               set active_flag='N',
                    inactive_date=sysdate
              WHERE prod_map_id = to_number(apex_application.g_f01 (i));    
  

  Could you please let me know how to disable it.

  Kind regards

• How to avoid the focus problem when browsing via browser back button

  Hello
  
  I am facing a problem in setting focus on the buttons.
  Please see application: http://apex.oracle.com/pls/otn/f?p=47869:2
  
  login details:
  Workspace: vsanthanam
  user: vijay
  PSWD: apex_demo
  
  In this application, I have 2 pages.
  #2 has the "submit" button
  Page no. 3 contains the Cancel button
  
  The two buttons are basic HTML and can be accessed using access key ALT + s and ALT + c.
  
  The problem is:
  When I go back to the previous page (pgid #2) of the application using back button of the browser pgid IE #3.
  due to the onFocus event located in the button "submit", control returns to pgid #3.
  
  Is there a possible way to set the focus to other elements. so that whenever IE brower back button, application would stay in
  page #2.
  
  
  I took approaches:
  -------------------------
  If we use onclick, onfocus instead and then the problem remains because we have onfocus = "this.click (); in equipping the Accesskey.
  Another way is onKeyup event. If we use onKeyup, we can avoid this browser back problem, but disappears from the access keys functions.
  
  Pointers on this would be a great help.
  
  Thank you very much
  -Vijay
  
  PLEASE NOTE: I have created intentionally two buttons on each page. It is necessary to have HTML buttons with the key features of access,
  otherwise application gives a few flaws in HTML accesskey.

  Hi Vijay,

  Crikey, aren't annoying browsers! It took a while to get out, but I've updated your SUBMIT1 button attributes:

  class="t20Button" AccessKey="s" tabindex="-1" onclick="javascript:this.blur();doSubmit('SUBMIT1');" onfocus="javascript:this.blur();doSubmit('SUBMIT1');"
  

  Note that I removed the spare semicolons you after each attribute - these are only required in javascript code.

  The important point to note are the statements of "this.blur" () - this tells the browser to move away from the current item to the next. On your page, only for this purpose, I have added a text element of Temp - I am assuming that your actual page will have at least one other element on the page that will accept the focus? Everything gets focus of the call "this.blur ()", should be the element with focus when the Back button is used.

• How to avoid to create images when importing duplicate?

  I doubt that it is the correct method or better to import/organize my photos, because it creates additional work I would like to avoid.  I'm looking for a solution.

  I do the following:

  • Copy all my photos from my SD card in my folders organized on my external hard drive.
  • Open Lightroom and import photosfrom my external hard drive.

  What happens is that Lightroom creates an image duplicated on my Mac in my pictures folder. At this point, he referred to this directory and not my external hard drive. What I end up doing deletes the pictures in my photos folder.  So I connect all my photos in Lightroom on my external drive.

  As you can imagine, it becomes tedious to do this every time I have import in Lightroom.

  My idea situation is Lightroom NOT to reproduce images or put them in any folder, but simply refer to those that I chose when importing to my external hard drive.

  Any help would be much appreciated.

  It's probably because you select the option COPY the top of import dialog when you should be by selecting the Add option.

  COPY the images of copies from one place to another and to import them.

  ADD add just the images in the LR catalog where they are currently.

  There is also the possibility of "make the second copy to:" on the side right of the dialog import but this option is only available with either COPY it, MOVE or COPY as DNG options. You need to add the option to add images in the catalog file LR in the place where they are already on your external drive.

• How to avoid overwriting the italics when you apply paragraph styles?

  First of all, let me say thank you to the community of Adobe's Forum for the great help over the years! You Rock! 9 times out of 10 you nail!

  OK, so I have a long document full of italics, bold and accents. Successfully, I imported the text in MS Word and kept these text features using the import options. But now, when I go to apply paragraph styles, the italics are lost. Is it possible to implement paragraph styles so that they maintain Roman, italic, bold and also special characters like accents? Thank you!

  Hi David: I just put upward (and record) queries for search/replace that I of course after you import all text. For example, I have one that is italic in the document and it goes to a character called italic style. Once I saved queries, it is very fast to run on all the stories at the same time. And once the local formatting is managed through character styles, it is intact by assigning paragraph styles.

• How to avoid using fractions of EPUB available pixels fixed.

  Apple said to avoid the use of fractional pixels for letter spacing, font size and text placement. Since then, sometimes in the conversion to html and css formatting. Is there a way I can control this?

  Someone had their book rejected because of this?

  Thank you!

  It is perhaps not the droids you are looking for, but a way to check after the fact would be to create a copy of your epub, rename the epub to [epubnam] .zip (change .epub to .zip) and then find the .0px, .1px, .2px generated css file... (if you're handy with regular expressions, you could do a little better by looking for------.) ([0-9] * px, I checked it quickly to regexpal.com, but more robust tests may be in order)

  If you find a fractional value, you could "fix" no closest fractional value which is not trash your design and repackage the epub.

  FWIW, I did a quick scan through my epub css and can't find any decimal values.

• How to avoid using oracle.jdbc.driver.OracleConnection

  I am new to Java, but recently, I have a project on support.

  Problem:

  solution worked on the 1.4 jvm, now on 1.7.

  Respectively, the oracle.jdbc.driver.OracleConnection class has been used.

  Now, I need class oracle.jdbc.OracleConnection to use CLOB.createTemporary (), but... I can't.

  According to the docs, just replace in the code and config files a declaration of the class on another. But I replaced all in all the files of configuration of no. and anyway, no there wasn't that oracle.jdbc.driver.OracleConnection was created. (there is no explicit declaration of the type of connection in the code, everything is configured in the config files)

  Project uses marven, mybatis - 3.1.1. Database: oracle 9

  Driver: ojdbc14 - 9.2.0.5.jar contains two classes: the oracle.jdbc.driver.OracleConnection (for backward compatibility) and oracle.jdbc.OracleConnection.

  The question is what do I need to use a second instead of the first.

  Maybe there are a few java cache? I do not know...

  Everyone knows?

  I solved the problem!

  This thread helped me: https://forums.oracle.com/thread/556426 ("I have to use classes12.zip for this work.")

  The main problem was the jdbc driver - I tried all the ones I found on the page of download of oracle and the only factor that does the job was classes12.jar (Oracle Database 10g Release 2 (10.2.0.1.0)). I replaced it in 'ORACLE_HOME\jdbc\lib\' and 'apache-tomcat\lib\.

  Each driver has its own bugs, and I also did different things, so I can't say that any replacement driver is enough. Te I changed the time zone database, run the tzupdater, vm set param - Duser.timezone = ""-07:00 ", may be something else."

  Thank you very much for the answer so detailed!

• How to avoid using the 'form' tag

  Hi all
  
  Is it possible to call a form of my FORMS_PATH site from the browser without using the format of tag in the URL?
  
  for example, this is my URL to call the form master.fmx--> http:// < machine >: < port >/forms/frmservlet? form = master.fmx, is what I want to call it without using the format of tag after the? in the URL.
  
  Thank you.

  You can configure your formsweb.cfg file to include a section for your application.

  Lets say you have a section called myApp in the formsweb.cfg file,
  Then you can use http:/.../forms/frmservlet?config=myApp to call the application

  Note: If ssoMode = true in the related section of the formsweb.cfg for the MyApp, then the signature will only kick in the first

  You can use a specific environment file (a copy of the default.env file to your app) and then specify this environment file in the section of the formsweb.cfg file MyApp.

  [myApp]
  envFile = myApp.env
  ssoMode = true
  form = MyAppFirstForm
  pageTitle = MyApp
  ...

  Hope this is useful

• SDO_NN cannot be assessed without using the index when put inside subquery

  Hi all

  I met a problem when you use the function sdo_nn to find the nearest neighbor. Here is my scenario:

  _ I have 2 customer and store tables.

  Customer table _ a client_ID and a 2D sdo_geom point

  _ Store table has store_ID and a 2D polygon sdo_geom.

  In the beginning, I have this query to find the nearest store to each customer as below:

  Select s.STORE_ID, c.CLIENT_ID

  store customer, s c

  where sdo_nn (s.MYPOLYGON, c.MYPOINT, 'sdo_num_res = 1', 1) = "TRUE";

  _It works as expected when it returns a table showing the nearest store each customer.

  _Now I want to count the number of customers who have the same nearest store:

  Select / * + INDEX (store store_spatial_idx, client_spatial_idx client) * / count (nearest_store. CLIENT_ID)

  from (select s.STORE_ID, c.CLIENT_ID

  store customer, s c

  where sdo_nn (s.MYPOLYGON, c.MYPOINT, 'sdo_num_res = 1', 1) = "TRUE") nearest_store

  Group of nearest_store. STORE_ID;

  This query generates the following error:

  Error report-

  SQL error: ORA-13249: SDO_NN cannot be assessed without using the index

  ORA-06512: at the 'MDSYS. MD", line 1723

  Hello Pinball,

  Oracle space tends to be a quite complex with many variables and moving parts.  We chatted about the group to a sort of FAQ or guidelines to help people like you submit questions that actually answers.  First of all, you really have to tell us the version of Oracle you are using.  Particularly the problems involving the optimizer, version down to the exact defined patch number is a good idea.  Secondly, you took the time to submit the question so I guess you want a response.  If you really want to see the answer and then providing an example is one of the most important things that you can do.  I'm going to do here for you, but in general people on this forum come and go and are often pushed into lurkitude, so if you want the coax to provide you with an example of work is the key.

  So I wrote this about 12 c (12.1.0.2.0) and everything works fine for me.  Then I moved back from 11 GR 2 (11.2.0.4.0) and of course, there are questions.  So I guess that you don't use flavor of 11g.  So at this point we can look at the docs and see for 11g, have you often need to specify which table is the head and that is the one that has the spatial index to use.
  http://docs.Oracle.com/CD/E11882_01/AppDev.112/e11830/sdo_operat.htm#SPATL1032

  Its rather interesting that the optimizer of 12 c knows what you want, when I had to squint myself at your request and to play a little with the refining.  Note that SDO_NN is sensitive, because the geometry of the main table should come second in the operator.  I did not know that on the top of my head.

  
  SELECT
  /*+ LEADING(c) INDEX(s store1_spx)  */
   s.store_id
  ,c.client_id
  ,MDSYS.SDO_NN_DISTANCE(1)
  FROM
   store1 s
  ,client2 c
  WHERE
  MDSYS.SDO_NN(
      s.shape
     ,c.shape
     ,'sdo_num_res=1'
     ,1
  ) = 'TRUE';
  
  SELECT
   ns.store_id
  ,COUNT(ns.client_id)
  FROM (
     SELECT
     /*+ LEADING(c) INDEX(s store1_spx)  */
      s.store_id
     ,c.client_id
     ,MDSYS.SDO_NN_DISTANCE(1)
     FROM
      store1 s
     ,client2 c
     WHERE
     MDSYS.SDO_NN(
         s.shape
        ,c.shape
        ,'sdo_num_res=1'
        ,1
     ) = 'TRUE'
  ) ns
  GROUP BY
  ns.store_id
  ORDER BY
  ns.store_id;
  

  So I think that is your answer.  Give it a shot and see if this fits the Bill.  Of course, moving to 12 c would be useful for such things.  It would be interesting to collect more examples of this kind of space thing where 12 c is the answer. Also, would be nice if we could mark somehow this discussion as applying only to 11g and earlier versions.

  See you soon,.

• using a Case statement to display the values of column even as table headers

  I have a database that has been set up kind of tricky, in that some tables are made up of columns that are field names and one link to another table that contain the data for these field... also names there ID displays as many lines instead of as a row of data. I would like to write a query to extract that information and display it as one line for each ID.

  example: table 1

  ID, name, itemresponse and itemcode, Description

  Dee Jones Childrens Hospital 123 SITE location

  123 dee Jones, Date of appointment next NEXTAPPT 22/04/2014

  123 dee Jones was on bedrest NOSHOW reason do not show

  I would like to have the display of data as a record on this same patient, instead of as 3 separate registers (with the Description column in table 1

  Table 2

  ID, name, place, Date of the next meeting, show no reason

  123 dee Jones Childrens Hospital 22/04/2014 was the bed rest

  Hello

  DATE is not a very good name for a column.  Use something like EVENT_DATE, that will not be confused with a keyword from Oracle, instead.

  I don't see something like this column in the CREATE TABLE statement.  He will always be the same value on all lines?

  Here's a way to get the results you requested:

  SELECT id

  first name | ' ' || LastName AS name

  Date of birth

  MAX (CASE WHEN item_code = "NEXTAPPT", THEN item_response END) AS next_appointment,

  MAX (CASE WHEN item_code = "LASTDATE" THEN item_response END) AS last_visit_date,

  MAX (CASE WHEN item_code = "SITE" THEN item_response END) AS location

  FROM mytable1

  GROUP BY id, firstname, lastname, dob

  ;

  Of course, I can't test it very well until you post INSERT statements for the sample data.

  I guess that 2 or more lines of the entry have the same id, then they will necessarily be first name last name, the name and date of birth, too.  No doubt they are standardized in your actual tables.

• The values just don't not properly using a case in a query

  Hello PL/SQL gurus and experts.
  
  I use Oracle Database 11 g Enterprise Edition Release 11.2.0.1.0 - 64-bit Production version
  
  I'll have the data in the table below-
  

  drop table stud_fact;
  create table stud_fact(stud_NM, LVL_CD,ST_DT_DIM_KEY,OVRNK) as select
  'ABG Sundal','H','20110630','175' from dual union all select
  'ABG Sundal','H','20120630','0' from dual union all select
  'ABG Sundal','Y','20111231','147' from dual union all select
  'ACF Intl','H','20110630','280' from dual union all select
  'ACF Intl','H','20120630','0' from dual union all select
  'ACF Intl','Y','20111231','418' from dual union all select
  'AK Invest','H','20110630','485' from dual union all select
  'ANZ','H','20120630','0' from dual union all select
  'Arbor','H','20110630','12' from dual union all select     
  'Arbor','H','20120630','21' from dual union all select
  'Arbor','Y','20111231','5' from dual ;

  I use the following sql to retrieve the output-
  
  Select stud_nm,
  (case when ST_DT_DIM_KEY ' 20110101 ', ' 20111231' and LVL_CD = 'Y' then OVRNK)
  on the other case when ST_DT_DIM_KEY ' 20110101 ', ' 20110631' and LVL_CD = 'H' then OVRNK
  ELSE ' 0'
  END
  END YRRK),
  (case when ST_DT_DIM_KEY ' 20120101 ', ' 20120631' and LVL_CD = 'H' then OVRNK)
  ELSE ' 0'
  LYRK END)
  OF stud_fact
  
  but it gives the output as.

  Hope the rank column is NUMBER. You need to make changes accordingly...
